The Charleston County School District (CCSD) has recently begun development of criterion-referenced tests (CRT) in different subject areas and for different grade levels. This paper outlines the process that CCSD followed in the development of math and language arts tests for grades one through eight and area exams for required high school courses. The test development process begins with a statement of instruction or an objective. Methods for making objectives testable include revision, creation of new objectives, or grouping objectives into domains. The test purpose and feedback desired should be a guide in making objectives testable. Blueprinting refers to outlining the content to be tested and requires the developer to decide which objectives to test and the number of items needed to test each objective. Test and item specifications provide guidelines for writing items for a given objective. Objectives identification and specifications development provide the foundation for item construction. The pilot test tries out items and administration procedures, obtains empirical data for item evaluation and test form composition, and obtains performance data from students. Decisions to eliminate or retain items for future test forms depend upon the analysis of test data and the preference of the instructional staff. (PN)
